Research Interests
Ontological reasoning, context awareness, personalised information delivery, ontology learning and ubiquitous computing.
About
In 2003 William completed his bachelor degree in Computer Science with first-class Honours from the University of Waikato in New Zealand. After that, he spent about 8 months with the Waikato Aero Club for his flight training and received his PPL (Private Pilot's Licence) in August 2004. In the same month, he started a PhD under Associate Professor Judy Kay's supervision with a university/faculty scholarship (UPA-cofunded). He is with the Computer Human Adapted Interaction group (formerly known as the Smart Internet Technologies Research Group) at the University of Sydney. In early 2004, he also received a top-up scholarship from the Smart Internet Technology CRC.
William's thesis is "Ontology Learning and Reasoning for Indoor Pervasive Environments". The objective is to build an adaptive scrutable ontology, which is able to adapt to contexts and people and may be scrutinised about its formation, and conduct reasoning with it in a context-aware system. The thesis aims to exploits three aspects of pervasive computing with this ontology: conflict resolution with context evidence, personalisation and privacy control.
